A New Method For Assessing Smoking Behavior In Orthopaedic Patients, David Gallacher Apr 2019

A New Method For Assessing Smoking Behavior In Orthopaedic Patients, David Gallacher

OHSU-PSU School of Public Health Annual Conference

“A New Method for Assessing Smoking Behavior in Orthopaedic Patients”

Background:Tobacco use is associated with post-operative complications and self-reporting often introduces a bias that underestimates the true exposure. Traditional tobacco testing methods, including serum cotinine are associated with issues of specificity, as they do not differentiate active smokers from those on nicotine replacement therapies (NRTs). This study intends to evaluate the effectiveness of point-of-care carbon monoxide (CO) breathalyzer test to assess patient smoking status and to differentiate active smokers from those using NRTs.

Methods:Eligible patients will be >18 years old and indicated for joint or fracture surgery at ...

Radial Head Stability In Anterior Monteggia Injuries: An In Vitro Biomechanical Study, Armin Badre Mar 2019

Radial Head Stability In Anterior Monteggia Injuries: An In Vitro Biomechanical Study, Armin Badre

Electronic Thesis and Dissertation Repository

Anterior Monteggia fracture-dislocations are frequently complicated by persistent radial head instability leading to suboptimal outcomes. In this biomechanical investigation using a cadaveric elbow motion simulator, we examined the effects of ulnar extension angulation, soft tissue disruption, biceps loading and elbow motion on radial head translation. Our results showed significant anterior radial head translation with progressive ulnar extension angulation, with greater soft tissue injuries and increased biceps loading (P=.000). There was no significant difference in radial head translation between simulated active and passive elbow flexion (P=.251). These findings support the importance of an anatomic reduction of the ulnar fracture ...

Ultrasound-Triggered Antibiotic Release From Peek Clips To Prevent Spinal Fusion Infection: Initial Evaluations., Lauren J. Delaney, Daniel Macdonald, Jay Leung, Keith Fitzgerald, Alex M. Sevit, John R. Eisenbrey, Neil Patel, Flemming Forsberg, Christopher K. Kepler, Taolin Fang, Steven M. Kurtz, Noreen J. Hickok

Department of Orthopaedic Surgery Faculty Papers

Despite aggressive peri-operative antibiotic treatments, up to 10% of patients undergoing instrumented spinal surgery develop an infection. Like most implant-associated infections, spinal infections persist through colonization and biofilm formation on spinal instrumentation, which can include metal screws and rods for fixation and an intervertebral cage commonly comprised of polyether ether ketone (PEEK). We have designed a PEEK antibiotic reservoir that would clip to the metal fixation rod and that would achieve slow antibiotic release over several days, followed by a bolus release of antibiotics triggered by ultrasound (US) rupture of a reservoir membrane. We have found using human physiological fluid ...

Orthopedics and Physical Rehabilitation Publications and Presentations

Background: Cancer rehabilitation is a rapidly growing diverse field in physiatry. This case provides an example where rehabilitation physiatrists played a crucial role in the pain management, education, and rehabilitation before and after a palliative amputation. Due to her limited resources, both in her home country and in her local community, she could not access appropriate care that may have prevented the need for amputation. Though amputation is not generally accepted as the first line of treatment for pain, there have been several reports of palliative amputation in metastatic cancer patients. In particular, fore quarter amputations have been reported in ...

Opioid Consumption After Orthopedic Surgery: Prospective Randomized Trial On The Effects Of Preoperative Counseling, Sage Vincent, Taylor Paskey, Elizabeth Critchlow, Erica Mann, Talia Chapman, Md, Kristin Sandrowski, Md, Asif Ilyas, Md

Phase 1

Introduction: Recently, there have been increases in morbidity and mortality associated with opioid medications. Physician overprescribing, particularly within orthopedics, contributes to large quantities of leftover opioids, leading to an increased risk of non-medical opioid use and abuse.

Objective: To understand the role of preoperative patient counseling on postoperative opioid consumption, a prospective randomized study was done, with the idea that patients receiving counseling would take fewer opioids than their control counterparts.

Methods: Patients undergoing elective outpatient orthopedic surgery at Jefferson affiliate hospitals were enrolled over a 3-month period. Patients were randomized to a control group or to receive preoperative counseling ...

Phase 1

Introduction: The utilization of ultrasound-guided peripheral nerve blocks in orthopedic surgery has increased in popularity as the anesthesia of choice for the management of perioperative pain. Peripheral nerve blockade has been shown to increase overall surgical efficiency, improve patient satisfaction, reduce postoperative narcotic use, and decrease the duration of facility admissions, while increasing overall cost-effectiveness. To date, scant literature exists regarding the safety and efficacy of ultrasound-guided supraclavicular blocks used in common hand surgery procedures, and the rate of neurologic and vascular complications remains unknown.

Objective: The purpose of this study was to examine the effectiveness and complication rate of ...


Comparison Of Visual Analog Pain Score Reported To Physician Vs Nurse In Nonoperatively Treated Foot And Ankle Patients, Trevor Mcbride, Bs, Maj Kevin D. Martin, Do, Cpt Jeffrey Wake, Do, Atc, Lt J. Preston Van Buren, Do, Cuyler Dewar, Bs Feb 2019

Comparison Of Visual Analog Pain Score Reported To Physician Vs Nurse In Nonoperatively Treated Foot And Ankle Patients, Trevor Mcbride, Bs, Maj Kevin D. Martin, Do, Cpt Jeffrey Wake, Do, Atc, Lt J. Preston Van Buren, Do, Cuyler Dewar, Bs

Phase 1

Background: Patient reported outcome measures (PROMs) are taking a more prominent role in Orthopedics as health care seeks to define treatment outcomes. The Visual Analogue Scale (VAS) is considered a reliable measure of acute pain. A previous study found that operative candidates’ VAS pain score was significantly higher when reported to the surgeon compared to the nurse. This study’s aim is to examine whether this phenomenon occurs in nonoperative patients. We hypothesize that patients’ VAS scores reported to the surgeon and a nurse will be the same

Methods: This study is a retrospective cohort of 201 consecutive nonoperative patients ...
